Current studies estimate the incidence of intensive care unit (ICU) admissions in pregnancy and the puerperium to range between 0.7 and 13.5 events per 1000 deliveries (Pollock, 2010). Most of these admissions are postpartum, and obstetric complications account for between 55 and 90 percent. The most common indications are hypertensive disorders of pregnancy, hemorrhage, and sepsis (Baskett, 2008; Chantry, 2008; Orsini, 2012; Pollock, 2010). Nonobstetric indications for ICU admission include maternal cardiovascular disease, pulmonary disease, cerebrovascular accidents, trauma, and anesthetic complications (Wanderer, 2013; Zwart, 2010).
